` Similar letters of reference indicatecorrespending parts in theseveral fi'gures.` Themature oflmywinvention consists in the peculiarfmeans employed for adjustingthe feed rollers, cutter cylinderand tongueand j groove cutters as will be presently shown and described. i

`To enable others skilled in the art to make and use myV invention, I will proceed i A, represents the frame of the machine of the usual form. j i B, isthe cutting cylinder, vand D,D, are the feed rollers,one pair` being placed at j j each side'of the cutting cylinders. The feed rollers are placed one over the other, as j usual, and they and also the cutting cylinder, occupy the sameposition on the frame A, asiniother planingmachines.` Thelower feed rollers 1D, have their axes running in fixed `or permanent bearings inthe frame A, as usualbut the axes of the upper rollers D, work inbearings (a) (a)1 which are suspended `on "the upper ends of vertical 1 rods (b), see Figs. 1 and 2. The upper ends .of the rods (b)` having short horizontal arms (lo) attachedto them, whicharms pass through` the bearings above the journals or axes of the rollers D, "the bearings (afbeingallowed toturn onthe arms (0).` The two bearings of` each roller D are connectedbya rod E, as clearly shown in Fig. 2. The rods (b) Apass through projections or `guidesla) on,` the frame A, and the lowerV ends ofthe rods (b) at each sideiof the i j frame A restupon a slide Flwhich works on vertical guide rods (e) (e) secured to the a ;full,"clearand exact;` description of the to describe its construction and operation.`

frame"A,`see Figs. 1, 2 and 3. To the lowerl end" offeach. rod (bf) there is: attached by a`pivot a lever'.` Hl having a weight I at one' end, fttingin a recess (g) intlie slide, see 1.y j 1 j J is a screw connectedA with' small' bevel gear wheels K, by which^ the slide F is moved upland down' upon the guide rods Both slides F are operated at once, or" attlie same. time, in consequence of' a shaft L byfwhich the gear wheelsK at each' sideA ofthe frame A; are connectedand made to move simultaneously' withA eachv other, see Figs. 2and 3. j j

The axis or" journals of the cutting,cyl` ind'er B", workinbearings (7i) which' are secured to the upper" ends of vertical shown. in' Fig. 1'. These rods; work through the projections or guides ("a')` on"l the frame, and a screw (j) passes throughb the lower projection or' guide (d) and through `a bar. ("Zclwhich isf connected to` the lbwer ends oftll'e' rodsjtz'f); @n the upper end of the screwY there isa bevel wheel (Z) which gears into a bevel wheel (m) on a shaft M, said shaft passing transversely through the frame A and having a bevel wheel (m) on its opposite end which gears into the wheel of the screw at the opposite side `of the frame, see Figs. 2 and 3.

N is a clamp at each side of the frame A and bearing against the rods (i). A rod O, passes through both clamps, said rod O` having a screw thread cut on one end which works in one of the clamps and a knob or thumb wheel P at the opposite end.

R, R', Figs. 1, 2 and 4, are the cutters which cutV `the tongue and groove of the plank or board. The cutter R-is permanent its shaft (In.) working Vin stationary bearings, but the cutter R is made adjustable the bearing' (p) of its shaft (71, having a screw rod S passing through it as clearly shown in Fig. 4, and by turning which the cutter R is brought nearer toor farther from the cutter R. The bearin (p) vhas a guide (r) to its bearing forme by elongatmg the bearing sufciently to allow a guide rod T to pass through it, the guidef rod being parallel with the screw rod S as shown in Fig. 4.

Each pair of feed rollers D, D are connected at one end by pinions (a) which gear into each other, see Figs. 1 and 2.

The operation of the machine so far as the planing of boards is concerned is precisely similar to other machines in use, the feed rollers forcing the board along underneath the cutting cylinder B, but the manner of adjusting the feed rollers D D is entirely different. By merely turning the shaft L, both slides F F may be raised or lowered and with them both of the upper feed rollers D', because the rods (b) rest or bear upon the slides F and rise and fall with it. The levers I-I give the requisite pressure to the rollers D and by this simple operation, the turning of the shaft L, both of the rollers D may, at the same time, be raised or lowered to suit planks or boards of varying thicknesses, and by means of the suspended bearings (a) the rollers D may be inclined to conform to the boards unevenly sawed or Which are thicker at one side than at the other, see red lines Fig. 2, thus preventing any strain or undue pressure upon the bearings, a diculty attending the planing machines in use.

The cutting cylinder B is raised or lowered by turning the shaft M, both ends of the cylinder being operated upon at the same time and by turning the rod O, the clamps N are made to bind against the rods (i) (i) and secure the cylinder B at the desired height. f

The arrangement of the guide (r)` and guide rod T keeps the adjustable cutter R firm and steady and allows it to be moved or adjusted With facility.

I do not claim any of the parts of the Within described machine irrespective of the devices herein shown for admitting of the adjustment of the feed roller and cutters, With the exception of these devices the parts described are substantially the same as the Woodworth and other planing machines. I do not claim the feed rollers and cutting cylinder for planing planks or boards for they have been previously used, but

lVhat I do claim as new and desire to secure by Letters Patent, is

1. I claim hanging the axes or journals of the upper feed rollers D in suspended bearings (a) attached to the rods (b) in the manner and for the purpose as herein shown.

2. I claim adjusting the cutting cylinder B, by having its bearings (It) (Il.) attached to vertical slide rods (i) operated bythe bevel Wheels (m) Z) and screws (j) and securing the cylinder at the desired height by means of the clamps N, N, and rod O, as herein shown and described.

3. I claim the employment or use of the guide rod T and guide (r) arranged as' shown for the purpose of keeping the adjustable cutter R firm and steady While operating and causing it to be adjusted With facility.
